Cloud
Moving a database to the cloud is a cutover project. The destination only helps if the application, the jobs and the recovery plan arrive with it.
For SQL Server the usual destinations are Azure SQL, Azure SQL Managed Instance, SQL Server on Azure or Amazon RDS, or SQL Server on EC2. For PostgreSQL, Aurora is one option and not the only one. Google Cloud SQL is in scope when that is the platform you have chosen. We do not treat one cloud as the default.
Service limits are on cloud and hybrid database services. Version upgrades that happen at the same time are on database migration services. A continuous copy during the move may use AWS DMS when the source and target support it.
Azure, AWS or Google Cloud, and whether the engine stays SQL Server. If the target service is undecided, that is a fine place to start.
